Technical Observations: The patina is dark green and red. The piece was cast solid by the lost-wax process. There may be striations going along the hilt, but they are mostly obscured by the green corrosion layer. There is a pseudomorph of an inlay material near where the hilt meets the blade; the grain of the preserved organic material extends along the length of the hilt. The material may have been bone or wood, but the metal is too mineralized for identification. There are visible impressions of a long fiber that may have resulted from the dagger’s adjacency to a fibrous object during burial.
There are striations visible under the green corrosion along the length of the blade. The edges of the tip are rounded, and there are no tool marks. Minor casting flaws are visible in the blade and hilt. The hilt and blade were cast in one piece. The crack across the blade and the bent section are visible. There are dark lines on the lower guard.
